Thanks, I should have added the following:
It's not EVERY time that it does this either... just to add to the fun
It's more than not, but every once in a while when I'm trying to replicate it, it will run just fine.
I just found a loose cable (appears to be a ground) from the valve cover that runs to the ignition coil and tightened it down snug. Took around the block a few times, no problems. I'm hoping that somehow that was the problem but I don't think I'll get off that easy as nothing with this car has been easy.
After tightening the ground for the ignition coil, I drove the car, without problem for about 5 minutes and let it cool off a bit. I let it sit for about an hour and just drove it 20 miles with no problems with a 20 minute stop in between.
When I got home, I thought I'd test my theory that the ground was the problem. So I loosened the nut and let the bracket swing freely, driving another 2 miles... without problem...
I'm going to try again in just a few minutes, it should be cold again, and I'll give it another whirl. I have other issues to work out, like oil that's dripping ever so slowly onto the exhaust manifold and a vacuum hose that has been disco'd and I have no clue where it goes... but for now, this is the problem that REALLY needs solving as it's affecting my daughter's ability to go to work and school.
I can try the ECT and thermo tomorrow, thanks for the advice!
